[0030] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0031] like Figure 1-4 As shown, a brake pad steel back punching device that is convenient for loading includes a punching table 1 and a conveying mechanism 2, wherein the conveying mechanism 2 is located at the front side of the punching table 1, and a punching mechanism 3 is provided on the upper side of the punching table 1;

[0032] The punching mechanism 3 includes a right-angled connecting frame 31, a puncher 32 and a first cylinder 33. The first cylinder 33 is assembled and connected between the puncher 32 and the connecting frame 31. A positioning plate 34 is assembled and connected to the lower side of the output shaft of the first cylinder 33.

[0033] The punching table 1 is rotatably connected to two rotating rods 41, and a rotating handle 411 is provided at the upper end of the rotating rod 41. One rotating rod 41 is provided with a thread on the upper part, and the other rotating rod 41 is provided with a thread on the lower end. The connecting frame 31 is fixedly connected to a fixing block 43. The upper ends of the two rotating rods 41 are rotatably connected to the fixing block 43. The two rotating rods 41 are sequentially connected with a limiting plate 44 for limiting the positioning plate 34 and a pressing plate 45 for positioning the brake pad from top to bottom. The limiting plate 44 is threadedly connected to the rotating rod 41 with a thread on the upper end and is slidably connected to the other rotating rod 41. The pressing plate 45 is threadedly connected to the rotating rod 41 with a thread on the lower end and is slidably connected to the other rotating rod 41. A limiting ring 46 is provided in the middle of the rotating rod 41.

[0034] By adopting the technical solution of this embodiment, the conveying mechanism 2 is used to convey the brake pad steel back to the punching table 1, the punching mechanism 3 is used to punch holes in the brake pad steel back, the first cylinder 33 controls the punching machine 32 to descend, the connecting frame 31 is used to assemble the first cylinder 33, the punching machine 32 is used to punch holes in the brake pad steel back, when the output end of the first cylinder 33 extends, the positioning plate 34 follows the output end of the first cylinder 33 to descend, the rotating handle 411 is used to rotate the rotating rod 41, when one rotating rod 41 is rotated, the limit plate 34 or the pressure plate 45 threadedly connected to the rotating rod 42 moves, when the positioning plate 34 moves downward and contacts with the limit plate 34, the positioning plate 34 stops descending, the first cylinder 33 is subjected to the force transmitted to it by the positioning plate 34, the first cylinder 33 stops descending, and the punching machine 32 stops descending, when drilling holes in the brake pad steel back, the descending position of the punching machine 32 is controlled at a specified position by controlling the height of the limit plate 34. The height of the pressure plate 45 is controlled by rotating the rotating rod 41 with a thread on the lower end, and the brake pad steel back is positioned to prevent the brake pad steel back from moving during the drilling process of the brake pad steel back; when in use, the brake pad steel back passes through the conveying mechanism 2 to reach the drilling platform 1, and the staff adjusts the position of the limit plate 34 according to the depth of the hole to be drilled on the brake pad steel back, rotates the rotating rod 41 with a thread on the upper end, and the limit plate 34 moves up and down. Then the staff aligns the position where the brake pad steel back is to be drilled with the lower end of the punching machine, and adjusts the position of the pressure plate 45 by rotating the rotating rod 41 with a thread on the lower end to fix the brake pad steel back. It should be noted that due to the large friction between the rotating rod 41, the fixing block 43 and the drilling platform 1, the rotating rod 41 will not rotate by itself, and the thread is self-locking, so when the rotating rod 41 is not rotated, the limit plate 34 and the pressure plate 45 will not move relative to the rotating rod 41.

[0035] Reference Figure 1The conveying mechanism 2 includes a conveyor belt 21 and a mounting frame 22. The conveyor belt 21 is assembled and connected to the mounting frame 22. The upper surface of the conveyor belt 21 is flush with the upper surface of the punching table 1. The mounting frame 22 is provided with a clearance groove in front of the punching table 1. The front side of the mounting frame 22 is assembled and connected with a pushing assembly 23.

[0036] In this embodiment, the conveyor belt 21 is used to transport the brake pad steel back, and the pushing assembly 23 is used to move the brake pad steel back from the conveyor belt to the punching table 1. The clearance grooves are opened on both sides of the mounting frame 22 to make the plane of the mounting frame 22 flush with the punching table 1. When the pushing assembly 23 senses that the brake pad steel back has arrived in front of the pushing assembly 23, the pushing assembly 23 pushes the brake pad steel back conveyor belt 21 onto the punching table 1 to complete the loading.

[0037] Reference Figure 1 The pushing assembly 23 includes a fixed plate 231, a pushing plate 232 and a second cylinder 233. The fixed plate 231 is fixedly connected to the front side of the mounting frame 22. The second cylinder 233 is assembled and connected to the upper side of the fixed plate 231. The upper surface of the fixed plate 231 is flush with the punching table 1. The pushing plate 232 is assembled and connected to the output shaft of the second cylinder 233. The lower side of the pushing plate 232 is slidably connected to the fixed plate 231 and the conveyor belt 21.

[0038] In this embodiment, when the brake pad steel back reaches the front of the push plate 232, the second cylinder 233 works to move the push plate 232 forward, moving the brake pad steel back from the conveyor belt 21 to the punching table 1, and the fixing plate 231 is used to install the second cylinder 233.

[0039] Reference Figure 2-4 : A buffer assembly 5 is provided on the upper side of the limit plate 44, and the buffer assembly 5 includes a first telescopic rod 51, a first spring 52 and a buffer plate 53. The first telescopic rod 51 and the first spring 52 are assembled and connected between the limit plate 44 and the buffer plate 53. The first spring 52 is located outside the first telescopic rod 51, and the buffer plate 53 is located below one side of the positioning plate 34. Slide rods 54 are slidably connected on both sides of the buffer plate 53, and a positioning column 55 is provided on the lower side of the slide rod 54.

[0040] In this embodiment, when the positioning plate 34 moves downward, the positioning plate 34 will contact 2 with the buffer plate 53 above the limit plate 44. When the positioning plate 34 moves downward, the first spring 52 is compressed by the force. During the compression process, the force applied to the buffer plate 53 by the first spring 52 gradually increases. When the positioning plate 34 can no longer move downward, the lower side of the buffer plate 53 contacts the upper side of the positioning column 55. The first spring 52 is used to prevent the positioning plate 34 from making hard contact with the limit plate 44 during the descent, thereby preventing a large impact force from being generated.

[0041] Reference Figure 1: Two symmetrically arranged pressure strips 451 are fixedly connected to one side of the pressure plate 45, and the two pressure strips 451 are located on both sides of the punch 32.

[0042] In this embodiment, the pressure strip 541 is used to increase the contact area with the steel back of the brake pad to prevent the steel back of the brake pad from moving.
